[Prior Art] 天线 The antenna structure is based on the current dipole antenna (dipole antenna). The size is not enough for portable portability, especially in the case of radio frequency identification (RFID), which is convenient for individuals to carry, usually The meander line antenna (meander line antenna Μ antenna is bent at least once to reduce the size of the appearance. ^ 埽 Refer to the figure, is a plan view of the proposed twisted antenna.

However, due to factors limited by half wavelength, The length and width are about 95mm and 38mm respectively. The above-mentioned various techniques can be said to reduce the size of the whole of the heavens by ensuring that there is a certain green color as much as possible through the twisted antenna. The size of the antenna is limited by the wavelength 舆 frequency ^ and the frequency of the number depends on the environment used by the celestial body. The antennas of the above-mentioned conventional technologies have their bandwidths mostly between 7〇Mhz and i 0〇Mhz, such as To reduce the size again, it is of course intuitive to use the twisted antenna. Zoom out, but in addition to changing the original characteristics of the antenna, it is more important that the quality factor (Q factor, Q: value) of the cable is reduced, and the width of the cable is narrowed, which is not true, so the antenna is In the technical field, it is necessary to reduce the size of the I-line and maintain the original bandwidth, which becomes an important lesson. For the sake of the job, the applicant has made a repetitive scrutiny in view of the lack of the aforementioned prior art. In this case, the following is a brief description of the case. ..... .
